HU 212 526 Β

The present invention relates to a sliding door, in particular to a vehicle, with at least one or two sliding doors mounted on rails and slidably disposed on a wire.

A known sliding door solution is described in DE-C 3 630 229. The door leafs of the two-leaf sliding door described herein are guided by rollers with vertical axes running in the lower and upper guide rails, which are pivotable about a vertical door frame tube and thereby the door leaf is flipped out of its closing plane.

The door's electric actuator is powered only during the movement of the door leaf, so that the door leaf is locked by a separate deadlock mechanism, which prevents the door door from being forcibly opened.

This deadlock mechanism only locks the door locks against opening, so that if for any reason the door cannot be completely closed, the door will be locked, for example, in the absence of locking. it may open due to vibration of the moving vehicle. A further disadvantage of the deadlock mechanism is that it requires precise adjustment, which is difficult to achieve due to the harsh application conditions and the large differences in temperature that are normally encountered.

A further disadvantage of the known solution is that the door frame tubes arranged at the side edges of the door frame cannot be covered with open door leaves, at most only in part and require a separate cover element. Uncovered door frame tubes are a danger especially for children and the elderly.

Door frame pipes also need to be mounted at the bottom, top, and adjusted in three dimensions, resulting in installation labor and possible malfunctions due to possible adjustment errors.

Other sliding sliding doors with pneumatic and hydraulic actuators are also known, e.g. is disclosed in AT-B 188 323. In this arrangement, the door wings are suspended on a sled, which is guided on a circular cross-sectional horizontal support tube and can be tilted around. In addition, the door wings are guided by rollers running in underside guide rails.

The actuating mechanism of the door wings may be a hydraulic or pneumatic cylinder, a locking mechanism may be provided with various scissor and lever arms. The locking of the door wings in the closed position is performed at the door frame side edges, with a built-in structure, and prevents the door wings from being opened during vehicle movement in the event of a drop in cylinder cylinder pressure. At the height of the handle, the locking mechanism that closes to the side of the door frame also poses a danger to passengers.

It is an object of the present invention to overcome the aforementioned shortcomings of the known solutions by simply inserting and / or inserting with little or no customization. with a sliding door design that eliminates the risk of accidental elements on the side frames of the door frame.

In the embodiment of the present invention, the actuator of the door leaf or doors comprises an electric motor driven spindle and associated actuator gripped with respect to the door leaf, the opposite end of the spindle gear being in the form of a locking and / or is equipped with a brake.

Preferably, there is a running surface for the door leaf on the door frame side facing the door frame side edge member, preferably near the upper edge of the door.

Preferably, the locking member is a roller disposed on a horizontal axis perpendicular to the direction of movement for closing the door leaf.

Advantageously, an additional running surface is provided on the door leaf directly above the locking member.

The advantage of the present invention compared to the prior art is that the brake or clutch combined with the freewheel forms a self-locking door locking device, without the need to arrange an accident-causing device at the side of the door frame. The present invention eliminates the need for both door frame tubes. The door locking elements of the present invention effectively prevent the door wings from being lifted, either by a passenger pushing the door or by a movement of the vehicle in six opening directions.

Figure 7 is a view of the interior of the vehicle of Figure 6.

The two door numbers 1, 2 of the vehicle door of Fig. 1 are suspended on slides 3 sliding and tilting over a cylindrical rail 4 above the door opening. Figure 1 does not show a threaded spindle driven by an electric motor driven door motors. The door opening is bounded on both sides by 9 door frame sides.

Figure 2 is a sectional view II-II of the door of Figure 1. In the upper part of the door, above the door opening, the cylindrical rail 4 is arranged with a slider 3 which can be slid and tilted thereon. The door leaf 2 is shown in the figure in the closed position, i.e. in the plane of the body, but also with thin lines in the upper part, the open position of the door 2 is also highlighted from the plane of the body.

The door apertures 1, 2 are guided by rollers 5 running in a guide rail 6 at the top, and rollers 7 running in a guide rail 8 at the bottom. The door frame side edge 9 is top and bottom

EN 212 526 Β clear of any risk of pinching of components throughout its height.

Figure 3 illustrates in greater detail the upper part of the door containing the drive. The electric motor 10 of the gear unit transmits the movement to the threaded spindle 12 by means of a chain or belt drive 11. On the spindle 12 there is arranged a drive nut 21 (Fig. 5) per door leaf, which is fixed to the slider 3 connected to the door number 1, 2, whereby the two door leafs open or close simultaneously depending on the direction of rotation of the spindle 12. To this end, the two halves of the spindle 12 are mirror-symmetrical (right and left-hand threads).

Figure 4 shows the upper corner of the upper part of the door away from the gear. The end of the spindle 12 is mounted in a freewheel housing 23 (Fig. 5) and forms an inner rotor of the freewheel. The external rotor of the freewheel is equipped with a brake. Figure 4 illustrates an emergency actuator 13 which releases the brake via actuator bar 14 when actuated by the actuator 13.

Figure 5 shows that the operating rod 14 is held by a spring 29 in its resting position. The emergency actuator 13 can be actuated through a pulling bar 15. In normal operation, the brake is released by pulling 16 pull-downs or, in the case of an electromagnetic clutch, by releasing it in a controlled manner.

Figures 4 and 7 further show a door locking device. The door 1, 2 has a running surface 17 adjacent to the door frame side edge 9, which is a substantially horizontal surface on which a roller 18 rests from above when the door leaf is closed. The axis 19 of the roller 18 is held in a holder (shown in Fig. 6) fixed at the side edge of the door frame 9. In the last section of the closing, the door leaf moves in direction 20, indicated by the dashed line in Figure 6, so that the running surface 17 of the door leaf 2 moves in the direction 20 towards the end of the closing movement. The axis 19 of the roller 18 is substantially perpendicular to the direction of the door movement 20 that completes the closing. It is also apparent from Figure 4 that the side edges of the door frame 9 are free and do not restrict the movement of the door wings. It follows that in the opening attempts there is a force acting perpendicular to the plane of the door wick, the resulting torque of which attempts to move the upper end of the door wick outwards, i.e. tilting the sledge 3 on the rail 4 outwards. This tilt of the slide 3 raises the door leaf 2 upwardly along the side of the door frame 9. This rise of the door is effectively prevented by the roller 18 which rests on the running surface 17. The effect does not depend on whether or not the door leaf or door leaf is closed. the height at which the locking device comprising the roller 18 and the running surface 17 is arranged on the door frame, that is to say at the height of head or above head where there is no danger of being pinched or malfunctioning due to operational dirt. The locking device is preferably located at the height of the upper door frame or at a height of approx. it is set so high that it is covered by the actuator casing.

Figure 5 illustrates, by way of example, a preferred embodiment of the freewheel and brake of the actuator, which is arranged on the side opposite the motor 10 of the spindle 12 of the upper part of the door. In the figure, the drive nut 21 of the slider 3 of the door 2 is located at the end of the spindle 12, which is typical of the open state of the door. The end of the spindle 12 is mounted in the freewheel housing 22 or grasping. The freewheel allows the spindle door 12 to rotate in the closed direction, even when the seat 22 is in a brake position.

It is possible to open the door leaves 1, 2 and to rotate the spindle 12 in the open direction when the brake is released, when the outer part of the freewheel - the nest 22 rotates with the spindle 12. The outer part of the freewheel is secured to the end of the shaft 24 mounted in the body of the vehicle or is made in one piece. On the shaft 24, a clutch disk 25 with friction discs 26 is arranged and secured by a latch against relative rotation. The clutch disc 25 is disposed between two brake discs 27,28 which are locked against rotation with respect to the body of the car and one of which is axially movable. The movable brake disc 27 is a mechanical and an electromagnetic actuator part of the actuator rod 14, which is provided with a spring force 29 arranged to clamp the clutch brake disc 27 to the clutch disc 25 at rest, brake. With the brake released, the freestanding nest 22 can rotate with the spindle 12 in the direction of opening the door leaves so that the door leaves can be opened.

The brake is released automatically during normal operation and manually in the event of danger with the 15 pulling towers. After manual operation, the brake can be opened or re-locked using a lever assembly (not shown), depending on what the operator deems appropriate. One option is advantageous because the door is operable immediately after opening, and the other option is because it can be detected and eg. unjustified emergency opening is punishable.

The freewheel and brake actuator according to the invention provides protection against accidental or unwanted opening of the door wings, not only when the door is fully closed, but over a wide range, and the protection operates automatically and does not require adjustment. This makes installation work easier, for example, without having to consider the width of the rubber seals used.

The invention is not limited to the embodiments described in the examples. The drive of the spindle 12 can be realized e.g. with chain drive or with a motor mounted concentric with the spindle directly.

The device for locking the door wings against lifting, comprising 18 rollers and a running surface 17, can also be implemented in various ways. To prevent only unauthorized opening by the user, the structure can be provided with two running surfaces spaced at short distances, which are thus lubricated and resistant to wear. In order to relieve the slides 3 and the rail 4 in the closed position of the door leaves, a locking device 3

EN 212 526 B has a running surface underneath and above the roller. Of course, the arrangement of the rollers and the running surfaces on the door frame can also be reversed. on the door leaves, so the rollers can also be arranged on the door leaves.

In a further embodiment, the freewheel with brake and bearing is located on the spindle 12 concentric therewith. A freewheel with brakes can be arranged on the vehicle ceiling, similar to a spindle gear, in which case a sprocket, gear or belt drive links the freewheel to the spindle. In addition to reducing the length of the construction, this solution has the advantage that both ends of the spindle 12 are supported by bearings and that the units can be separately mounted without tension.

The brake can be designed as a friction clutch or a form-fitting clutch.
